fix(armor_yolo_detect): pass full image to correctCorners for ROI detection

In processROIs, armor coordinates are converted to global image
coordinates before calling correctCorners. However, the function was
incorrectly receiving roi_gray (ROI local image) instead of the full
input image, causing coordinate system mismatch in findSymmetryAxis.

This fixes corner refinement accuracy when using fitLine-based light
detection in ROI-cached detection modes.
